YOU CAN HEAR THE CHANTS. THOUSANDS OF PEOPLE HAPPY AND CLEARING -- CHEERING AND CLAPPING THAT THE SUSPECT WAS TAKEN AWAY. SEAN MCDONALD JOINS US FROM WATERTOWN WITH MORE DETAILS ON HOW THE CAPTURE UNFOLDED. GOOD MORNING. GOOD MORNING TO YOU, JOSH. THIS IS WHAT IT -- WHERE IT CAME TO AN END ON FRANKLIN STREET. THE ONE JUST TO THE LEFT THERE WHERE THIS ALL CAME TO AN END YESTERDAY. THE MASSIVE MANHUNT, AND JUST WHEN IT LOOKED LIKE POLICE WOULD NOT COME UP WITH ANYTHING, IT WAS A RESIDENT IN THIS HOUSE THAT NOTICED SOMETHING STRANGE, SOME BLOOD ON A BOAT HE STORED IN HIS BACKYARD. HE WENT OUT THERE AND SAW THE SUSPECT, DZHOKHAR TSARNAEV AND CALL POLICE. AND POLICE ENGAGED IN AGAIN AND A GUN BATTLE, BUT THIS TIME THEY CAPTURED THE SUSPECT ALIVE AND RESIDENTS AROUND HERE, THEY COULDN'T BE HAPPIER. [APPLAUSE] CHEERS AND RELIEF FRIDAY NIGHT. JUST SO RELIEVED IT IS ALL OVER. AFTER SPENDING THE DAY IN THEIR HOMES, WATERTOWN RESIDENTS LEARN THE SUSPECT, 19- YEAR-OLD DZHOKHAR TSARNAEV WAS FINALLY CALLED. INVESTIGATORS GOT A 911 CALL FROM A RESIDENT WHO SAW SOMETHING SUSPICIOUS IN A BOAT BEING STORED IN HIS BACKYARD. IT WAS JUST OUTSIDE THE AREA POLICE HAD BEEN SEARCHING ALL DAY. THEY WANTED DZHOKHAR HAD CLIMBED UNDER THE PLASTIC WRAP TO HIDE. POLICE MOVED IN AND ENGAGED THE SUSPECT. THE MEN WHO FOUND HIM AT THE BOAT SAID HE WAS COVERED WITH BLOOD. WE ASSUME THE INJURIES OCCURRED THE EVENING BEFORE. THERE WAS AN EXCHANGE OF GUNFIRE AT THE BOAT. I DON'T KNOW IF HE WAS STRUCK. THIS IS VIDEO OF THE TEAM BEING RUSHED FROM THE SCENE TO THE HOSPITAL. IT ENDED A WILD 24 HOURS IN WHICH POLICE SAY MARATHON BOMBING SUSPECTS DZHOKHAR TSARNAEV AND HIS OLDER BROTHER TAMERLAN CONTINUED TO TERRORIZE THE AREA. ROBBING A STORE, SHOOTING AND KILLING AN MIT OFFICER, CARJACKING A MAN AND GETTING INTO A SHOOTOUT WITH POLICE. TAMERLAN WAS KILLED BUT DZHOKHAR FLED ON FOOT, LEADING TO THIS UNPRECEDENTED MANHUNT FRIDAY IN THE BOSTON AREA WHERE RESIDENTS WERE TOLD TO STAY IN THEIR HOMES. WHEN IT ALL ENDED, WATERTOWN RESIDENTS EMERGED ON THE STREET CHEERING. HAPPY TO BE OUT HERE CELEBRATING OUR FREEDOM. THANK THE POLICE AND ALL THE WONDERFUL PEOPLE WHO MAKE THIS HAPPEN. THE QUESTION NOW, WHAT HAPPENS TO THE 19-YEAR-OLD SUSPECT, WANTING -- WANTED FOR KILLING AND INJURING SO MANY PEOPLE. THE FEDERAL DEATH PENALTY IS ON THE TABLE. WE ARE GOING TO BE REVIEWING ALL THE EVIDENCE. BEFORE THAT KIND OF A DECISION IS MADE, IN TERMS OF WHETHER OR NOT TO SEEK THE DEATH PENALTY , YOU REVIEW ALL OF THE EVIDENCE. AND IT IS A VERY FULL, LONG PROCESS. AND IT IS THE ATTORNEY GENERAL OF THE DEPARTMENT OF JUSTICE THAT MAKES THAT FINAL DECISION. AGAIN, A LIVE LOOK THERE AT THE HOUSE WHERE THIS ALL CAME TO AN END LAST NIGHT. IT IS LIT UP, BY THE WAY, BY INVESTIGATORS. WE CSPI OFFICIALS AS WELL AS STATE POLICE, STILL WORKING THE SCENE AND COLLECTING -- WE SEE THE FBI OFFICIALS AS WELL AS THE POLICE. DZHOKHAR TSARNAEV IS STILL IN THE HOSPITAL IN SERIOUS CONDITION. POLICE WANT TO QUESTION HIM ON
